Indicate whether the statement is true or false (Question 2) Overlap in the innate and adaptive immune system is seen in all of the following examples but one. Which of the following examples does not illustrate the overlap of innate and adaptive immune responses? A) Dendritic cells presenting antigens on their MHC II proteins to T-helper cells. B) Plasma cells that produce large amounts of IgE that will ultimately allow mast cells to release histamine. C) NK cells causing apoptosis of an abnormal host cell, lacking MHC proteins. D) Macrophages becoming activated macrophages in response to cytokines released by T-helper cells. (Question 3) Which of the following INCORRECTLY describes mechanisms of CO2 transport? A) as bicarbonate ions in plasma B) 7-10 of CO2 is dissolved directly into the plasma C) just over 20 of CO2 is carried in the form of carbaminohemoglobin D) attached to the heme part of hemoglobin (Question 4) The primary immune response ________. A) has a lag period while B cells proliferate and differentiate into plasma cells B) is another name for immunological memory C) occurs more rapidly and is stronger than the secondary response D) occurs when memory cells are stimulated (Question 5) The paired lungs occupy the mediastinum of the thoracic cavity. Indicate whether the statement is true or false (Question 6) B-lymphocytes are categorized as part of the adaptive branch of the immune system for all of the following reason but one. Which of the following is not one of the reasons B-lymphocytes are considered part of the adaptive immunity? A) Their receptors will bind to only one antigen. B) They are a first line of defense that can begin killing pathogens immediately. C) They require costimulation from an activated T-helper cell. D) They produce memory cells when activated. (Question 7) Clonal selection of B cells ________. A) occurs during fetal development B) cannot occur in the presence of antigens C) results in the formation of plasma cells D) only occurs in the secondary immune response (Question 8) Which of the choices below is NOT a role of the pleurae? A) allow the lungs to easily glide easily over the thorax wall during breathing movements B) assist in blood flow to and from the heart because the heart sits between the lungs C) help limit the spread of local infections D) help divide the thoracic cavity into three chambers (Question 9) Increased temperature results in decreased O2 unloading from hemoglobin. Indicate whether the statement is true or false (Question 10) The largest amount of carbon dioxide is transported in the bloodstream in the form of carbonic anhydrase.
